Here at the Flame Trench is the Columbia display that will go on tour.
"The fact that NASA is using, for the very first time, recovered Columbia pieces -- that obviously has real impact when people see it," KSC spokesman Allard Beutel said. "People have had an emotional response."
A cockpit switch panel is displayed behind the glass.
The Columbia crew would have used it to control the fuel drain and purge system on the shuttle's lefthand orbital maneuvering engine, which propelled the spaceship onto its final trajectory.
The Crew Module Side Hatch Pyro-Initiator T-Handle also is displayed. It would have been used to jettison the orbiter's side hatch had the astronauts been able to bail out of the shuttle.
Here is the Florida Today article about the display.
